Fuel Tank info needed

[Examiner]

1. Need to know largest size for an outside above ground storage dual wall tank that is allowed without a vault or dikes?

2. If more than one tank; what would be the separation distance required between the tanks and a fuel canopy?

3. Will a fuel canopy be considered to be a building? I think the answer to this one is NO. There are not any walls.

4. Will size and/or location be different if the fuel is gasoline or diesel?

I do not have any NFPA books to research the above. Could not find anything in the 2006 IFC on fuel tanks.

I seem to remember that above ground tanks had to be 30-ft from buildings.

Any input is welcome.

What will they be used for?? Generator??

Or is this to run to gas pumps to fuel vehicles???

Appears you are under IFC for design

From IFC appears Table 22.4.1.1(a) of NFPA 30 applies for

Does not appear in the base code there is a limit size, we limit it by admendment

To answer the canopy question;;;

2704.13 Weather protection. Where overhead noncombustible construction is provided for sheltering outdoor hazardous material storage areas, such storage shall not be considered indoor storage when the area is constructed in accordance with the requirements for weather protection as required by the International Building Code.

Exception: Storage of explosive materials shall be considered as indoor storage.

Look at NFPA 30 and 30A for fuel tanks.

Thank you all. I will review the sections you listed as well. Mark listed a "Coffee Shop" site in a recent post under Commercial Fire Codes found in this forum. It has some information / Table regarding sizes of tanks. I do not know if the project is in a rural area or not. I am helping another Architect with Code research and I just started on after I got his email. I will have to compose a list of questions for him for items unknown at this time.

I do not have a copy of the NFPA and do not know any Architects or Engineers who do. Those books a too expensive for the times we have to go to them for information. I have never worked for a Governmental Agency or a Professional in the Private Sector who had the complete set. Some may have NFPA 10 in the Library and a few other volumes and even those are old editions when I reviewed them.
